Filtration device for flowing water

In Wasserlungseysteraen especially with central heating systems, depending on the water quality, a considerable amount be contained in pest and sole arar particles, which in fittings, pumps, regulators, etc. to unpleasant disturbances being able to lead. It is known to trap these foreign bodies with dirt filters.

In addition to dust particles, sand or similar particles, heating water contains, for example, tail pearls »flakes of scale and iron oxide caused by corrosion in Form of magnetite. This is in the heating water in finely divided form and calls the often encountered black Coloring.

As a noble material, the existing Elsenoxyde give rise to increased corrosion in heating systems. This is true especially for systems with mixed metal materials such as B. iron, copper and non-ferrous metals. The corrosion will also supported by penetrating oxygen. One of the unpleasant consequences of corrosion is the formation of Hydrogen, which can lead to significant disruptions in the operational process. A perfect filtering of the iron oxides is therefore absolutely necessary to avoid this type of corrosion.

Commonly used in water pipe systems Filters are not suitable for separating the oxides. If the dimensions are too large, the fine oxide particles flow unhindered through the filter with the water or the filter is clogged in a relatively short time if the mesh size is too small *

The present invention relates to a filtering device for flowing water through which both the mud and sand particles and the Iron oxides are deposited.

This is achieved by having one known per se Filter a magnet for separating magnetizable! solid particles is connected upstream.

This filtering device has the following advantages:

A safe separation of all impurities, including the finest iron oxide particles, is possible. The service life of the filter is extended because the iron oxides are already be caught in front of the filter. The device can be built to save space.

The accompanying drawing represents exemplary embodiments of the invention. Show it:

Fig. 1 and Flg. 2: Two possible designs of the filtering device in cross section and FIG. 3? The design of the magnet in longitudinal section.

The valve housing 1 is connected with the two ends, 2, J> to the line network. Inside the filter 4 a rod-shaped magnet 5 is arranged so that this magnet is first washed around by the flowing water. To prevent corrosion on the magnet, it is surrounded by a waterproof sleeve 6 made of a non-magnetizable material, such as plastic. According to Pig. 2, the sleeve has elevations 7 on the surface, which ensure that the finest oxide particles are reliably caught even at high flow rates.

The cleaning takes place in the training according to FIG. 1 such that the plug 8 is unscrewed and with the rod-shaped magnet 5 and the filter 4 from the fitting housing 1 is removed. By pulling the magnet out of the sleeve 6, the firmly adhering oxide particles can also be removed easily removed.

In the training according to Pig. 2 can be the valve body 1, which z. B. consists of a transparent plastic jacket, can be removed by loosening the union nut 9. In this case, cleaning is also possible without opening the housing 1 by removing the magnet 5 from the sleeve and the parts sinking into the dirt collector Io are removed by unscrewing the plug 11.
